Benefits of technology

[0010] In one example, the neural network generates the data set, which comprises a plurality of coefficients for providing future time information based upon a starting time input. In one example, the neural network is trained repeatedly until a desired level of accuracy is provided by a data set.
[0011] The various features and advantages of this invention will become apparent to those skilled in the art from the following detailed description. The drawings that accompany the detailed description can be briefly described as follows.

Problems solved by technology

There is the possibility for losing communication with the GPS.
It is necessary to maintain accurate timing information during intervals where communication with the GPS is not possible or otherwise not reliable.
The internal timers of typical base stations do not provide accurate enough time information to be reliable for more than very brief time periods.
Other available sources of information, such as local time information, do not provide globally accurate time information.

Embodiment Construction

[0016]FIG. 1 schematically illustrates selected portions of a wireless communication system 20. A base station controller 22 controls communications through a base station in a generally known manner. The base station controller 22 receives timing information from a global position system (GPS) 24 using available techniques. The timing information allows the base station controller 22 to maintain continuous and accurate communications as required within the wireless network.

[0017] There are instances where effective communication between the base station controller 22 and the GPS 24 are not possible. For such situations, the illustrated arrangement includes a future time data set 26 for providing time information during intervals where communication with the GPS 24 is lost. A neural network 28 generates the future time data set 26, which in one example includes a plurality of coefficients for providing future time information based upon an input starting time.

Abstract

A wireless communication system (20) includes a base station controller (22) that receives timing information from a data set (26) that is generated by a neural network (28). The data set (26) allows for generating timing information based upon previous time information received from a GPS (24) and in one example, is capable of covering a time interval of up to two weeks during which effective communication with the GPS may be interrupted. In one example, the data set is continuously updated so that the base station controller (24) continuously has up to two weeks of future time information available.

Description

FIELD OF THE INVENTION [0001] This invention generally relates to controlling timing information for a wireless communication system base station. More particularly, this invention relates to generating a data set that is useful for providing future time information for a base station. DESCRIPTION OF THE RELATED ART [0002] Wireless communication systems are in wide spread use. Typical configurations include areas that are effectively divided into cells. A base station typically is responsible for handling communications for mobile units within a corresponding cell. In some instances, more than one base station may be provided for an individual cell. [0003] Base station controllers rely upon timing information to maintain accurate communications. This is especially true for communications that extend outside of a cell associated with a particular base station. Where the CDMA protocol is used, timing synchronization is critical for continuous and accurate communication. [0004] Timing ...
